Problems solved by technology

However, since natural water treatment has just started, there are few microbial agents for river eutrophication
However, microbial agents suitable for industrial wastewater are not suitable for river water bodies that differ greatly in water quality from industrial wastewater.

Embodiment 1

[0016] A compound microbial preparation for river course management, comprising compound microorganisms, said compound microorganisms are composed of the following raw materials in weight percentage: 2% of Purecoccus nitrous, 5% of Thiobacillus oxidans, 8% of Paracoccus denitrificans, Bacillus 30%, Rhodospira 10%, Lactobacillus 15%, Saccharomyces cerevisiae 10%, Bacillus subtilis 20%.

[0017] A kind of preparation steps of the composite microorganism preparation for river course management is:

[0018] 1) Each microorganism is expanded and cultivated separately:

[0019] Pure coccus nitrous: Pure coccus nitrous is cultured on a nitrous bacteria culture medium at 28-30°C, first on a slant, then on a secondary seed liquid, and then mixed and fermented until the bacterial concentration reaches 1-2×10 8 individual / mL. The nitrosating bacteria culture medium: 0.5 g of ammonium sulfate, 0.3 g of sodium chloride, 0.03 g of ferrous sulfate, 1 g of dipotassium hydrogen phosphate, 0....

Abstract

The invention relates to the technical field of microbes, and especially discloses a composite microbial preparation used for river treatment. The composite microbial preparation used for river treatment comprises a compound microorganism, and the compound microorganism is composed of the following raw materials in percent by weight: 1-2% of nitrosococcus, 5-8% of thiobacillus thiooxidans, 8-15% of paracoccus denitrificans, 20-30% of bacillus spp, 8-18% of rhodospira, 6-15% of lactobacillus spp, 10-15% of saccharomyces cerevisiae, and 20-30% of bacillus subtilis. After being poured into polluted water, the composite microbial preparation used for river treatment is capable of obviously improving the water body blackening smelliness problem, reducing water-quality ammonium nitrogen and total phosphorus content, decomposing hydrogen sulfide and other harmful substances and improving water body environment. The composite microbial preparation used for river treatment is capable of improving the absorption utilization efficiency of water plants on nutrition elements and obviously improving the water body transparency, and possesses the advantages of stabile microbial preparation, strong purification capability, simple preparation, low cost and applicability to river treatment.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a composite microorganism preparation for river channel management. Background technique [0002] With the growth of population and the development of urban construction, a large number of human activities have had a huge impact on natural water bodies, and a large number of pollutants are directly discharged into rivers, resulting in organic matter, ammonia nitrogen, total phosphorus, H 2 Harmful substances such as S continue to increase, and the natural purification capacity of water bodies is seriously insufficient. [0003] Adding microbial agents to eutrophic or polluted water bodies can effectively improve the purification ability of natural water bodies and resist the impact of water pollution. The application of microbial preparations to rivers improves the ecological environment of water bodies, inhibits and kills pathogenic microorganisms, and makes beneficial b...
